Answer:
A.It leads Odysseus to devise a plan to trick the Trojans.
Explanation:
In the Iliad, Calchas a prophet tells the Greeks that the captured Chryseis must be returned to her father Chryses so that the gods would stop afflicting them with the plague. Achilles and Agamemnon quarrel and fall out because Agamemnon requests that Breseis, Achilles' slave be used as a replacement for Chryseis.
This angered Achilles who refused this proposal and as a result, refused to keep fighting in the war, which caused massive loss of men for the Greeks.
King Odysseus seeing that they were losing the war, had to devise the trick of the Trojan Horse to defeat Troy.
